Python减肥计划的代码

以下是一个简单的 Python 减肥计划的代码示例，包括设置目标、制定计划、监督进展和调整计划的功能：

import datetime

class WeightLossPlan:
    def __init__(self, goal_weight, goal_body_fat):
        self.goal_weight = goal_weight
        self.goal_body_fat = goal_body_fat
        self.start_date = datetime.date.today()
        self.weight = None
        self.body_fat = None
    
    def set_weight(self, weight):
        self.weight = weight
    
    def set_body_fat(self, body_fat):
        self.body_fat = body_fat
        
    def get_progress(self):
        if self.weight is not None and self.body_fat is not None:
            return {
                'weight': self.weight,
                'body_fat': self.body_fat,
                'date': datetime.date.today() - self.start_date
            }
        else:
            return None
    
    def adjust_plan(self):
        progress = self.get_progress()
        if progress is not None:
            if progress['weight'] > self.goal_weight:
                print('You need to adjust your diet and exercise plan to reach your weight loss goal.')
            if progress['body_fat'] > self.goal_body_fat:
                print('You need to adjust your diet and exercise plan to reduce your body fat.')
        else:
            print('No progress has been made yet.')
    
    def print_plan(self):
        print('***WEIGHT LOSS PLAN***')
        print('Start date:', self.start_date)
        print('Goal weight:', self.goal_weight)
        print('Goal body fat:', self.goal_body_fat)
        
    def print_progress(self):
        progress = self.get_progress()
        if progress is not None:
            print('***WEIGHT LOSS PROGRESS***')
            print('Date:', progress['date'])
            print('Weight:', progress['weight'])
            print('Body fat:', progress['body_fat'])
        else:
            print('No progress has been made yet.')

这个代码示例定义了一个 `WeightLossPlan` 类，用于管理减肥计划。在初始化对象时，需要设置目标体重和目标体脂肪。然后，可以使用 `set_weight()` 和 `set_body_fat()` 方法来设置当前的体重和体脂肪。`get_progress()` 方法返回当前的进展情况，包括体重、体脂肪和距离计划开始的天数。`adjust_plan()` 方法根据进展情况来调整计划，如果进展不如预期，则需要调整饮食和锻炼计划。`print_plan()` 方法用于打印计划的详细信息，包括开始日期、目标体重和目标体脂肪。`print_progress()` 方法用于打印当前的进展情况。可以根据需要添加更多的功能和方法。
